Spas

Spas and Hot Tubs are great fun but evidence shows they are also very good for the Human Body. Immersion in hot swirling water has been known for centuries for its medicinal benefits. At water temperature of 35ºc there is an increase in cardiac output of up to 35% and these changes are magnified with increasing temperatures, so that at 37ºc the cardiac output is increased to 100%. The body is exercised as much by using a spa/hot tub as it would be jogging.
